      NB: there used to be some code here which set the initial size of the

          that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
          it. To see why, you should understand that Windows sends WM_SIZE from
          inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
          from some base class ctor and so this WM_SIZE is not processed in the
          real class' OnSize() (because it's not fully constructed yet and the
          event goes to some base class OnSize() instead). So the WM_SIZE we
          rely on is the one sent when the parent frame resizes its children
          but here is the problem: if the child already has just the right
          size, nothing will happen as both wxWidgets and Windows check for
          this and ignore any attempts to change the window size to the size it
          already has - so no WM_SIZE would be sent.
